During a tuning flight I found no airspeed ,no distance from home and pos hold or RTH not working ,I have taken off inside the radius of a Safehome

Steps to Reproduce

unable

Expected behavior

correct display of info on osd and correct functioning

Additional context

Blackbox and DVR failed to load in github I have the recordings

I dont understand why I cant upload the files!

Works fine for me. This is likely a setup problem. So this should be a discussion, not an issue.

this is the dvr at the end,please look at the stats
the issue is that everything was working fine,and through my pre and post flight inspection i didnt find any problem with the aircraft

When you armed the FC, You may have had 7 Sats. But the GNSS module didn't have a 3D fix. So it only had a very poor indication of home.
Plus your HDOP was very poor throughout most of the flight. Leaving the Speed, Altitude and distance to home, intermittent and sketchy at best.
Try looking for anything that is close to your GNSS module, and is emitting RF noise. Like the VTX or a receiver with telemetry.
Plus place HDOP on your OSD.. A 3D fix normally occurs below 2.0... It displays position accuracy (lower the better) and is more important than the number of satellites.

First of all thank you for your time🙏
The strange thing is that is the same place where I fly usually,and the aircraft hasn't changed before this flight.
I will for sure put HDOP on osd and will see how it behaves,thanks!

It could have been the poor satellite positioning in the sky at that time of the day.. This can often lead to this effect if your GNSS module doesn't get a clean fix most of the time anyway.
